For me, it justs gets the floor tom lower. I used to low ride behind my kits (can't do that anymore ... with my new titanium hip) ... so all my floor toms got flipped. Very few companies knurl their floor tom legs full length, so rather than try to clamp onto smooth metal rod, I flip my floors 180. Now that I have to sit a little higher, my floors might all wind up right side up, again. We shall see.

I have the opposite problem. I wish my floor tom legs were longer! I've just raised all my toms and they're much better now they're higher but I cannot get the floor tom to a high enough level. It's not uncomfortable to play at all but it could do with another four inches of height.
